Oxidant and antioxidant signalling in plants: a re-evaluation of the concept of oxidative stress in a physiological context
Christine H. Foyer,Graham Noctor +1 more
TL;DR: It is proposed that the oxidative stress syndrome would be more usefully described as 'oxidative signalling', that is, an important and critical function associated with the mechanisms by which plant cells sense the environment and make appropriate adjustments to gene expression, metabolism and physiology.
